Which of the following has the highest value of resistivity? / निम्नलिखित में से किसका प्रतिरोधकता का मान सर्वाधिक है? [SSC CGL 17 July 2023, 1st Shift]
Answer
Correct Answer : b ) Nichrome / नाइक्रोम
Explanation :Resistivity measures how much a material resists the flow of electrical current.
Nichrome, an alloy of nickel, chromium, and iron, has a very high resistivity due to its composition.
This high resistivity makes it ideal for applications such as heating elements in electrical equipment.
Hence, (b) is the correct answer.
प्रतिरोधकता मापती है कि कोई पदार्थ विद्युत धारा के प्रवाह का कितना प्रतिरोध करता है।
निकेल, क्रोमियम और लोहे का एक मिश्रधातु, निक्रोम, अपनी संरचना के कारण बहुत उच्च प्रतिरोधकता रखता है।
यह उच्च प्रतिरोधकता इसे विद्युत उपकरणों में तापन तत्वों जैसे अनुप्रयोगों के लिए आदर्श बनाती है।
अतः, (b) सही उत्तर है।
